The PAC031AR.14 Visible Achromatic Doublet Lens is a 430 to 700 nm antireflection coated, 1/2 inch (12.7 mm) diameter, N-BK7 and N-SF5 precision achromatic doublet lens with an effective focal length of 63.5 mm. This achromat is computer designed to effectively minimize spherical aberration and coma when operating at infinite conjugate ratio, yielding smaller focused spot sizes. Unlike singlet lenses, this results in a constant focal length independent of aperture and far better off-axis performance. Achromats are superior to singlet lenses for monochromatic applications at any visible wavelength.
